Despite its long history in the public eye, the diamond still prompts many questions. Was the Hope Diamond cut from the great French Blue Diamond that was stolen during the French Revolution in 1792? Are there other blue diamonds that were cut from the same original parent stone as the Hope Diamond? Why does the Hope Diamond emit an intense ember-orange glow after exposure to ultraviolet light? Recent research highlighted elsewhere on this web site has attempted to unlock these and other secrets of the Hope Diamond. A 3-D computer modeling study explored the cutting history of the Hope Diamond and investigated whether other diamonds could have been cut from the Hope Diamond parent stone. A second project used a variety of spectroscopic methods to probe the luminescence behavior of the Hope

Diamond, including the orange phosphorescence, and compare it to more than 70 other blue diamonds. In addition to providing insights into the cause of the phosphorescence, the study suggested that the particular phosphorescence behavior of a blue diamond might serve to uniquely identify that stone.

Diamonds have a long history as beautiful objects of desire. In the first century AD, the Roman naturalist Pliny stated: “Diamond is the most valuable, not only of precious stones, but of all things in this world.”

A diamond has to go through a lot before it reaches the jeweler’s display case. It forms deep in the earth under extreme heat and pressure. It’s ejected violently upward until it arrives at or near the earth’s surface. It’s forced from its hiding place by nature or by man. Then it’s cleaved and cut and polished until its natural beauty shines through.

The world’s love of diamonds had its start in India, where diamonds were gathered from the country’s rivers and streams. Some historians estimate that India was trading in diamonds as early as the fourth century BC. The country’s resources yielded limited quantities for an equally limited market: India’s very wealthy classes. Gradually, though, this changed. Indian diamonds found their way, along with other exotic merchandise, to Western Europe in the caravans that traveled to Venice’s medieval markets. By the 1400s, diamonds were becoming fashionable accessories for Europe’s elite.

Surprisingly, diamonds share some common characteristics with coal. Both are composed of the most common substance on earth: carbon. What makes diamonds different from coal is the way the carbon atoms are arranged and how the carbon is formed. Diamonds are created when carbon is subjected to the extremely high pressures and temperatures found at the earth’s lithosphere, which lies approximately 90-240 miles below the earth’s surface.

Until the 18th century, India was thought to be the only source of diamonds. When the Indian diamond mines were depleted, the quest for alternate sources began. Although a small deposit was found in Brazil in 1725, the supply was not enough to meet world demands.

The diamond is more than just aesthetically beautiful—it’s an enduring symbol of love, romance, and commitment. The stone’s name is derived from the Greek word adamas, which translates to “unconquerable.” This symbolic meaning lends itself well to the diamond’s historic commemoration of eternal love.

Today, the world’s diamond deposits are slowly becoming depleted. Less than 20% of the diamonds mined are of gem quality; less than 2% are considered “investment diamonds.” 75-80% of mined diamonds are used for industrial applications, such as grinding, sawing, and drilling. Typically, more than 250 tons of ore must be mined in order to produce a one-carat, gem-quality stone.

The diamond’s rarity, beauty, and strength make it a fitting symbol of the resilience and longevity of marriage. In addition to engagement rings, diamonds are traditionally given as gifts to commemorate the milestone of the sixtieth anniversary. With their rich history, sense of permanence, and lustrous brilliance, diamonds are a natural choice to signify a lasting union.ZA

In 1947, DeBeers commissioned the services of leading advertising agency N.W. Ayer, and the slogan “A diamond is forever” was coined. The premise of this large-scale marketing campaign was the suggestion that diamonds should be the only choice for engagement rings. The DeBeers advertising campaign was wildly successful, and . In today’s fine jewelry market, more than 78% of engagement rings sold contain diamonds.

With the surge in popularity of the precious stone, many companies and organizations began campaigns to educate jewelers and consumers about what to look for when selecting a diamond. As jewelers experimented with ways to enhance the diamond’s visual appeal and presentation, new cutting techniques were adopted to hwas a contributing factor to today’s widespread embracing of the tradition of diamond

The use of rings as a symbol of commitment dates back to ancient history, specifically to the betrothal (truth) rings of the Romans. These early rings, often formed from twisted copper or braided hair, were worn on the third finger of the left hand. The placement of the ring was significant, as Romans believed that a vein in the third finger (vena amorous) ran directly to the heart. For Romans, betrothal rings were given as a sign of affection or friendship, and did not always represent the rite of marriage.

The history of the engagement ring began in 1215, when Pope Innocent III, one of the most powerful popes of the Middle Ages, declared a waiting period between a betrothal and the marriage ceremony. The rings were used to signify the couple’s commitment in the interim. It was around this same time that rings were introduced as a major component of the wedding ceremony, and it was mandated by the Roman government that all marriage ceremonies be held in a church. In addition to serving as symbols of an intention to marry, these early rings also represented social rank; only the elite were permitted to wear ornate rings or rings with jewels.

In 1866, 15-year-old Erasmus Jacobs was exploring the banks of the Orange River when he came across what he thought was an ordinary pebble, but turned out to be a 21.25-carat diamond. In 1871, a colossal 83.50-carat deposit was unearthed on a shallow hill called Colesberg Kopje. These findings sparked a rush of thousands of diamond prospectors to the region and led to the opening of the first large-scale mining operation which came to be known as the Kimberly Mine. This newly discovered diamond source increased the world’s diamond supply substantially, resulting in a significant decrease in their value. The elite no longer considered the diamond a rarity, and began to replace this “common” stone with colored gemstones. Emeralds, rubies, and sapphires became more popular choices for engagement ring stones among the upper class.

6.-3 COLOUR, COLOUR FILTERS, AND THE DICHROSCOPE

While ruby and supphire are the red and blue varieties of the mineral corundum, there are also white, yellow, pink and green supphires. emerald and aquamarine are the rich green and pale blue varieties of beryls, but there are also white, pink, and yellow beryls, and green beryl that do not rank as emeralds, tourmaline, quartz, zircon and topaz are further well-known examples of such polychrome minerals, and tourmaline in particular 

is well known for frequently appearing as parti-coloured crystals, the boundaries between the colours -(usually green and pink) being quite sharp either across the length of the crystal or concentrically in zones. the reason of such confusing behaviour can usually be explained by the fact that there are a limited number (eight to be precise) of elements that give rise to colour in minerals.

Diamond History

The earliest diamonds were found in India in 4th century BC, although the youngest of these deposits were formed 900 million years ago. A majority of these early stones were transported along the network of trade routes that connected India and China, commonly known as the Silk Road. At the time of their discovery, diamonds were valued because of their strength and brilliance, and for their ability to refract light and engrave metal. Diamonds were worn as adornments, used as cutting tools, served as a talisman to ward off evil, and were believed to provide protection in battle. In the Dark Ages, diamonds were also used as a medical aid and were thought to cure illness and heal wounds when ingested.

As the Indian diamond supply dwindled, smaller finds occurred in Borneo and Brazil, but these were not sufficient to meet the ever-increasing demand for diamonds. The mid-nineteenth century discovery of diamonds near the Orange River in South Africa sparked the world's biggest diamond rush, and helped to satiate the world's increasing appetite for diamonds. back to top

Recent Times

During the mid-nineteenth century, diamonds were also being discovered in eastern Australia. However, it was not until late 1970's, after seven years of earnest searching, that Australia's alleged potential as a diamond producer was validated.

On October 2nd 1979, geologists found the Argyle pipe near Lake Argyle: the richest diamond deposit in the world. Since then, Argyle has become the world's largest volume producer of diamonds, and alone is responsible for producing over a third of the world's diamonds every year.

The Dark Ages The diamond was also used for some time as medical aid. One anecdote, written during the Dark Ages by St Hildegarde, relates how a diamond held in the hand while making a sign of the cross would heal wounds and cure illnesses. Diamonds were also ingested in the hope of curing sickness. During the early Middle Ages, Pope Clement unsuccessfully used this treatment in a bid to aid his recovery.

 back to top The Middle Ages

During the Middle Ages more attention was paid to the worth of diamonds, rather than the mystical powers surrounding them. Due to the heightened public awareness of the value of diamonds, mine owners perpetuated myths that diamonds were poisonous. This was to prevent the mineworkers swallowing the diamonds in an attempt to smuggle them out of the mines.

The popularity of diamonds surged during the Middle Ages, with the discovery of many large and famous stones in India, such as the Koh-I-Noor and the Blue Hope. Today India maintains the foremost diamond polishing industry in the world

HISTORY OF DIAMONDS

Early History

From myths about valleys of diamonds protected by snakes, to the production of millions of carats in rough diamonds each year, the history of diamonds is one of mystical power, beauty and commercial expertise.

Early History

The first recorded history of the diamond dates back some 3,000 years to India, where it is likely that diamonds were first valued for their ability to refract light. In those days, the diamond was used in two ways-for decorative purposes, and as a talisman to ward off evil or provide protection in battle.

5-2..DOUBLE REFRACTION AND DISPERSION

As would appear in a singly refractive stone such as diamond, each edge appears as a double line (see figure 3.1). a word of warning, however, should be uttered here; according to their crystal structure, all doubly refracting stones have either one or two direction in which only single refraction obtains. those gemstones belonging to the tetragonal, trigonal or hexagonal system of crystals have only such direction; one 'optic axis' as it called. these minerals, which are grouped together optically us 'uniaxal', 

include zircon, corundum (ruby and sapphire), beryl (emerald and aquamarine), tourmaline, and quartz (amethyst and citrine). the minerals crystallising in either the orthorhombic, monoclinic or triclinic systems have two optic axes, and are called 'biaxial'. these include peridot, chrysoberal (alexandrite), topaz, and spodumene (kunzite) among the coommoner gemstones.

3.COLOUR, COLOUR FILTERS, AND THE DICHROSCOPE

Colours plays an extermely important part in contributing to the beauty and popularity of precious stones. it was their colour that made such stones as turquoise and lapis lazuli among the first to attract the cupidity of early civilised man, and it is the

mangnificent crimson red of ruby, the deep cornflower blue of the finest sapphires and the verdant green of emerald which (added to their transparency, hardness and rarity) have caused them always to rank amongst the supremely precious gems. only in the case of diamond, unique in this as in so many other ways, has a complete lack of colour been  regarded as the standard of perfection. those unversed in gemmology find it hard to realise that is most of the mineral species used as gems a wide colour range is possible, and that in their 'pure' state they would be colourless and thereby of relatively little value.

4-1.REFRACTIVE INDEX AND ITS MEASUREMENT

It has already been stated that each mineral has a definite refractive index by which it can be identified on the refractometer; list of these indices will be found on p. 27, and at the of the post. for the benefit of those who like to have at least a rough idea of the working of an instrument which they are using, a short description of the basic principle upon which all gem-tasting refractometer depend followers. however, those, who would like to know how to use a refractometer, but who prefer to shirk such explanation, can 

skip the next section and await the strictly practical directions which will be given later, on p.21. what followers can best be understood by considering the diagram, figure 2.2. here rays of light are considered passing from a dense medium into a rarer one, say from glass into air. the rays will then be refracted away from the normal, NOM (the revers process of the former case considered in figure 2.1).

2.DOUBLE REFRACTION AND DISPERSION

In some minerals the figures very somewhat; thus in zircon, while the blue, white, and golden 'fried' type most popular in moderan jewellery are almost constant in their birefringence of 0.059. many of the ceyclonese zircons. particularly the green varieties, have a much lower double refractions, sinking in some cases practically to zero. this peculiaity is unique amongst minerals, and will be discussed at greater length in the chapter on zircon. synthetic rutile has been manufactured in the USA (since 

1949), and its anormous double refraction will be one means of identification. calcite, though not a gemstone, plays an important part in gemmological instruments in its optocally pure form of 'ice land spar', how, apart from the refractometer, can one test whether a given stone doubly refractive or not? the simplest method of all, which with a little practice is quite easily carried out, is to examine the stone carefully with a powerful pocket lens-say giving 8x to 12x magnification. for example, look trougth the table facet of a zircon with a lens, and focus sharply on to the edges of the back facets where they adjoin the culet, and it will be noticed that instead of a single sharp line where the facets join.

7.-1 REFRACTIVE INDEX AND ITS MEASUREMENT
Thus the ray AO is refracted along OA', apart from the small fraction of light which is reflected at O, as indicated by the dotted line. similarly, the ray BO is refracted along OB', as we consider rays which form greater angles with the normal, NOM, we reach an angle where the refracted ray only just grazes along the surface, OQ, between the two media. this angle is know as the critical angle, and all ray reaching O form the

denser medium at angle greater than the critical angle are totally reflected back into the denser medium, it being physically impossible for any light form such rays to penetrate into the rarer medium. in the post, the angle COM can be considered as the critical angle of incidence; all the light s thus totally reflected along OC", and any other rays, such as DO, with a still larger of incidence, is, of course, also totally reflected. it is important to realise that the size of the critical angles will depend upon the relations between the reflactive indices of the denser and the rarer medium.
